Hey all, absolute beginner here so please bear with me

We're finally pulling the trigger on a Colorbond reroof, wide quotes have been all over the place, and now I'm getting confused by something I didn't even know was a thing two weeks ago apparently there are different profiles? And now every roofer we speak to is either recommending Klip-Lok or Trimdek and I have no idea which one is actually better for us or if it even matters.
